You are a necromancer and your goal is to build army of skeletons and enter the gate. Each skeletons must have their own lavalamp as a key to enter the gate. Beware of dogs! They love bone and will most likely to steal yours. Don’t starve to death, eat some pizza. In nightmare mode, don’t forget to feed your skeletons or they’ll go back to sleep. Btw, every dungeon is unique, so there’s no need to memorize it.
